Question about Reddy Heater-30-55,000 BTU Variable

1 Answer

Model rem55pv or Rlp55v propane

If you hold the starter button in, it works fine. my guess is the thermocouple. How do you check it with a millivolt meter. The thermocouple also has two prongs for wires attached to it. Should there be about .030 volts in it? What are the two wire concectors for?

The thermocouple seems to be working fine. You should be getting around .025 volts-- I assume yours is rounding up as it should max out around .028 volts.

At this point you should check the relay- DESA states:

Thermocouple Turn off gas supply. Remove thermocouple from gas valve. Using a digital multi-meter set to the lowest DC millivolt setting (meter needs to have alligator clips on ends of leads), clip black lead to the very tip of thermocouple (end removed from valve). Clip red lead to the outer casing of thermocouple for ground. Relight unit output should be between 18 and 28 millivolts. Relay Turn off gas supply. Remove bottom of base (if equipped). Relay is a normally open circuit between terminals 4 and 6 which closes when current is supplied. Using a digital multi-meter measure the resistance. With no power to unit, resistance between terminals 4 and 6 is open circuit or no resistance. Apply power to relay. Resistance between terminals 4 and 6 should be less than 100 mili ohms.

My all-pro propane heater will not stay lit for over thirty seconds after I release the red fuel start button,before the flame goes out it makes an air hissing noise right before it shuts off.Heater will...


This sounds like a problem with your thermocouple.

Just remove the end of the thermocouple from where is goes into the gas valve and leave the end that goes into the flame in place.

Clean the end of the thermocouple connect by scraping off just a little metal from the end just about there the nut tightens the thermocouple into the gas valve. After you have exposed some new metal do the same inside the valve where the thermocouple seats into the gas valve.
Use a small pic or similar item to scrape inside the gas valve to expose some new metal there also.

Now reassemble the thermocouple into the gas valve and see if the heater works.

Here is a link with some more instructions.

If this does not solve the problem you may need a new thermocouple and you can find that at www.desaparts.com

Bob, it sounds as if either the thermocouple or the relay is defective. Below is a link to troubleshoot your parts: http://www.reddyparts.com/test-thermocouple.htm

Desa unvented propane log heater pilot will not stay lit


check to make sure that the end of the thermocouple is in the flame. This is the hot junction of the thermocouple and it the difference in temp that create the millivolts to operate the gas valve. If it is in the flame, replace it and if a new thermocouple doesnt fix it, you need a new gas valve

Reddy heater will not keep running


Test the thermocouple: Normal 0 Heater will run as long as the control valve is pressed.
According to DESA test these parts. NOTE: Not all heaters are equipped with
A relay.


Thermocouple
Turn off gas supply. Remove thermocouple
from gas valve. Using a digital
multi-meter set to the lowest DC millivolt
setting (meter needs to have alligator clips
on ends of leads), clip black lead to the
very tip of thermocouple (end removed
from valve). Clip red lead to the outer casing
of thermocouple for ground. Relight
unit output should be between 18 and 28
millivolts.
Relay
Turn off gas supply. Remove bottom of
base (if equipped). Relay is a normally
open circuit between terminals 4 and 6
which closes when current is supplied.
Using a digital multi-meter measure the
resistance. With no power to unit, resistance
between terminals 4 and 6 is open
circuit or no resistance. Apply power to
relay. Resistance between terminals 4 and
6 should be less than 100 mili ohms.

Need a replacement thermocouple for my DynaGlo Pro job site heater. Propane fueled, model RMC-FA4ODGP. Any suggestions ?


All thremocouples have a number on them which tells what 'millivolt' output it has. Try to match that up or call a HVAC company and ask them for one with that number.

Propane heater wont work


I'm not sure about that model, but I think you have to hold that button down for a minute or more to "prime" it.

I have a different model coleman propane heater that sits on the 20# tank. Mine is probably getting rusty, last time I used it I had to hold that button down for a long time.

I'm looking for a new heater now myself, as mine won't stay lit outdoors in much wind.

Won't stay lit..


I contacted ReddyParts.com and talked with their support department (866-883-9312). They instantly stated "your thermal coupler is bad". They had 1 in stock for 19.99 + shipping. I ordered it and plan to have it installed and tested by next weekend. The model I have is Reddy Heater Propane 35k to 55k (RLP55V).

Reddy propane heater RLP100


Try a little longer, sometimes it takes a full minute to heat the thermocouple. Check and make sure thermocouple is in flame. If all this is ok. then your going to have to change the valve.

Millivolt Generator burnout


I would check the pilot orfice to make sure you have enough of a flame to heat up the generator. You can buy a orfice drill bit and drill it out one size. The pilot should hit the generator toward the center. You should be able to buy a new orfice for the pilot assembly from the place you bought your heater.

Forced air propane heater won't stay lit


two items come into play here - 1) the hot surface cutout and 2) the flame detect Cd cell. Check alignment of the Cd cell or just replace it. The hot surface cutout has two terminals that plug into the two tabs on the millivolt generator.
